Sixteen parties for one house: where cost surprises are really born

The exact count
Sixteen parties, fifteen handoffs, one purchase.
Nobody ever gives you the full list. So here it is. To buy a new home in Quebec today, a household must coordinate sixteen separate parties, and repeat to each one the same identity, the same income, the same lot and the same dwelling spec. Taken on its own, each step runs about as fast as it can. The waste is not in the steps: it is in the fifteen handoffs between them. Here is where they sit, what they cost, and what changes when the whole thing happens in one place.
The sixteen parties, named
Land vendor or real estate broker. Municipality, for zoning and the permit. Land surveyor, for the certificate of location. The factory, the modular manufacturer. General contractor or installer. Excavation and foundation. Mortgage broker. Lender. Mortgage insurer, CMHC, Sagen or Canada Guaranty. Home and builder's risk insurer. GCR, for the warranty. Notary. Registre foncier, the land registry. CRA and Revenu Québec, for the GST and QST rebates. Hydro-Québec and municipal services. Building inspector. Sixteen. Not one of them talks to the other fifteen. Not one of them holds the complete file. The party who connects them is you: you carry the information from one office to the next, and you are the only person who knows what each one was told.
The fifteen handoffs, where the cost slips
Between sixteen parties there are fifteen handoffs. At each one, the same information is re-keyed by hand: your identity, your income, the lot dimensions, the dwelling spec. Every re-entry opens a wait state and introduces a discrepancy. And the discrepancy is not visible at the time. It resurfaces weeks later as a cost surprise. A zoning constraint discovered after the land is bought. A hookup that was in nobody's estimate. A change authorized before anyone priced its effect on the cost and on the date. This is not bad luck: it is what the structure of the journey produces.
What it looks like when it all happens in one place
At Modulabs, the purchase is eight steps and a single file: define, locate, prepare, confirm, buy, monitor, modify, conclude. You give your information once. Zoning, servicing and delivery access are verified on the chosen lot before you commit. The displayed price is the all-in price: house, land, foundation, hookups, transport, taxes and rebates. And the possession date is written down before you buy, not estimated afterwards. One meeting remains. Quebec law requires the deed of sale and the hypothec to be received by a notary, remote when your notary accepts it. One appointment, against sixteen parties: that is the whole gap.
What we take away from this
The waste is not in the steps. It is in the fifteen handoffs.
